Dmitriy V. Ryaboy commented on PIG-2397:
----------------------------------------
Interesting, tasks take much longer (10 secs vs your ~5s indicated by the
numbers) to set up on my cluster, probably due to overall pressure on the JT.
Thanks for running the numbers for Hive.
I'll profile a few map tasks on Q1 to see where it's spending time.

> For a class project we developed a whole set of Pig scripts for TPC-H. Our
> goals are:
> 1) identifying the bottlenecks of Pig's performance especially of its
> relational operators,
> 2) studying how to write efficient scripts by making full use of Pig Latin's
> features,
> 3) comparing with Hive's TPC-H results for verifying both 1) and 2).
> We will update the JIRA with our scripts, results and analysis soon.
